Galatians 2

1Then after a period of fourteen years I went up again to Jerusalem with Barnabas, taking Titus also with me.

2I went up by revelation, and I laid before them the Good News which I preach among the Gentiles, but privately before those who were respected, for fear that I might be running, or had run, in vain.

3But not even Titus, who was with me, being a Greek, was compelled to be circumcised.
